If you wanna hear some of the worst licks, check out the ones contributed by the In Flames guy, or Dan Spitz from Anthrax. Hell, guys from Lamb Of God and God Forbid contributed riffs, for christ's sake...
Or Dragonforce. Come on, an Amaj7 arpeggio? Not only is it easy to play, theory wise, it's way below just about everything else.
